Description
Technical Field
The invention belongs to the technical field of sanitary article manufacturing equipment, in particular to the fields of sanitary napkins, paper diapers, pull-up pants, sanitary pants and the like, and particularly relates to an online composite process system and a composite core product.
Background
In the prior art, the composite absorbent core body without fluff pulp is generally of a layered structure, and the structure is mainly composed of dust-free paper, high molecular water-absorbent resin (in the form of particles, which are simply called high molecular or SAP or high molecular materials), non-woven fabrics, high molecular and dust-free paper from top to bottom, wherein the high molecular is respectively arranged on the upper surface and the lower surface of the middle non-woven fabric, and hot melt adhesives are used between the materials. Because the polymer can absorb hundreds of times, even thousands of times of the liquid of the polymer and firmly lock the liquid after absorbing the liquid, the traditional composite core has a structure with a plurality of double-sided applied polymers, and the core structure is relatively complex. Because the composite core body is of a layered structure, the composite core body is not expanded integrally after absorbing a large amount of liquid, but is easy to break and delaminate between the non-woven fabric and the polymer after absorbing a large amount of liquid, and the composite core body after absorbing liquid for many times is slow in absorption speed, can generate side leakage, is easy to expand and harden and the like, and can cause discomfort of a user and even lead to compression or friction of a part contacted with a body.
The prior composite core body also adopts fluffy non-woven fabrics as the middle non-woven fabrics, but the fluffy effect is generally not ideal, so that the high molecular weight is less, and the diffusion speed is low; in order to increase the utilization of the voids between the lofty nonwoven fibers to accommodate more macromolecules, the core structure may be simplified. In the process flow of manufacturing the composite core product, the fluffy non-woven fabric is difficult to avoid tension and draft problems due to the characteristics of the material in the conveying and high polymer compounding processes, so that the width of the fluffy non-woven fabric is narrowed, the self-porosity structure of the fluffy non-woven fabric is damaged, and the high polymer is influenced to enter the fluffy non-woven fabric. Therefore, it is necessary to provide an online composite process system to effectively improve the production efficiency of the composite core and the utilization rate of the composite core.
Disclosure of Invention
Aiming at the defects or shortcomings of the prior art, the invention aims to provide an online composite process system and a composite core product, wherein the system has high production efficiency, and can utilize negative pressure in a composite drum device to suck high polymer particles into a fluffy non-woven fabric to be fully and uniformly mixed with the high polymer particles, so that the thickness of the composite core is effectively reduced, the manufactured product has the characteristics of no fault, no lump formation, no swelling, no hardening and the like, and the quality and wearing comfort of the composite core product are greatly improved; the composite core product is a single-layer application structure of the high polymer material, and the high polymer particles can enter into gaps between the fluffy non-woven fabric fibers and the fibers by utilizing the structural characteristics of the fluffy non-woven fabric, so that the fluffy non-woven fabric and the high polymer material are fully fused into a whole, and the absorption performance of the composite core is greatly improved.

Wherein in the present embodiment, the complex drum device J rotates in a clockwise direction.
The polymer feeding device F is connected with the motor, and can adjust the feeding weight of the polymer material F03 by controlling the rotating speed of the motor, and can continuously or discontinuously feed the polymer material F03 by controlling the rotation and stop of the motor.
At the upstream station of the composite drum device J, the fluffy non-woven fabric F02 and the coated non-woven fabric F01 are respectively arranged on a conveying route and are compositely fixed at the first clamping driving roller C01, and a first fixing glue G01 station is arranged on the coated non-woven fabric F01 before compositing, so that the fluffy non-woven fabric F02 and the coated non-woven fabric F01 can be bonded and fixed. The first clamping driving roller C01 is used for clamping and driving the materials of the coated non-woven fabric F01 and the fluffy non-woven fabric F02, so that the adhesive force between the coated non-woven fabric F01 and the fluffy non-woven fabric F02 is increased, and the materials are driven at the same time; the driving roller in the first clamping driving roller C01 is connected with a motor, and the speed of the station coated non-woven fabric F01 and fluffy non-woven fabric F02 can be adjusted by controlling the rotating speed of the motor. The second pinch driving roller C02, the third pinch driving roller C03, and the fourth pinch driving roller C05 described below are identical in structure and function to the first pinch driving roller C01.
The coated non-woven fabric F01 and the fluffy non-woven fabric F02 are clamped and fixed through a first clamping and pressing driving roller C01, a first semi-finished product F 'is formed after the lamination, and then the first semi-finished product F' is gradually conveyed to the circumferential surface of a lamination drum device J. Wherein, a plurality of induced draft areas are arranged inside the composite drum device J, and the induced draft areas are connected with an externally connected induced draft device, namely, a plurality of induced draft areas are arranged inside the composite drum device J, and the surface of the composite drum device J is adsorbed to a semi-finished product in a plurality of specific area ranges while a peripheral conveying drum J4 (described below) rotates.
Further, the embodiment further includes a fluffing roller device E and a fourth pinch driving roller C05, which are sequentially disposed between the first pinch driving roller C01 and the composite drum device J, where the fluffing nonwoven fabric F02 and the coated nonwoven fabric F01 are subjected to pinch compounding by the first pinch driving roller C01, and after the fluffing roller device E is fluffed, a first semi-finished product F' is formed after the driving by the driving roller under the fourth pinch driving roller C05, that is, when the fluffing roller device E is used in the process, the pinch above the fourth pinch driving roller C05 is selected not to be used. However, in order to ensure that the position of the first semi-finished product F' on the first pinch driving roller C05 is not changed in the stopped state, a whole set of fourth pinch driving roller C05 is adopted, and when the machine is restarted, the pinch roller above the fourth pinch driving roller C05 is separated from the driving roller below again. The fluffing roller device E fluffs the whole fluffy non-woven fabric F02, so that the fluffy degree of the fluffy non-woven fabric F02 can be improved, and a good condition is provided for the next station to adsorb the high polymer material F03. The fluffing roller device E is connected with a motor, and the fluffing speed of the fluffing roller device E can be adjusted by controlling the rotating speed of the motor.
Further, a free roll D is provided on the material conveying line, the number and position of which are determined according to the flow direction and the requirement, and the bonded fluffy nonwoven fabric F02 and the coated nonwoven fabric F01 form a first semi-finished product F' which is transferred into the composite drum device J under the guidance of the free roll D.
The polymer discharging pipe F1 in the polymer feeding device F is arranged at the first compounding position on the compounding drum device J, the polymer material F03 conveyed by the polymer feeding device F is gradually applied to the surface of the first semi-finished product F ' to form a second semi-finished product F ', and different negative pressure induced draft pressures are carried in A, B, C areas in the compounding drum device J, so that most of the polymer material F03 applied to the surface of the first semi-finished product F ' can be sucked into the fluffy non-woven fabric F02 under the action of the air draft pressure in the area B and the characteristic that the fluffy non-woven fabric F02 has fiber pores. Since the surface of the bulk nonwoven fabric F02 has fibers and fiber interlacing sites, a small amount of the polymer material F03 remains on the surface of the bulk nonwoven fabric F02.
Wherein, macromolecular material F03 gets into the fluffy non-woven fabrics F03 in-process of first semi-manufactured goods F ', and cladding non-woven fabrics F01 is pressed close to compound drum device J's surface, because cladding non-woven fabrics F01's width is greater than fluffy non-woven fabrics F03's width, guaranteed macromolecular material F03 blanking position regional negative pressure absorption stability, avoided the negative pressure differential problem that macromolecular material F03 appears in the unloading position of both sides. In addition, since the width of the coated nonwoven fabric F01 is larger than that of the fluffy nonwoven fabric F03, even if the polymer material F03 on both sides leaks, the polymer material F03 only leaks on the coated nonwoven fabric F01, and thus the polymer material F03 is prevented from being scattered in the area outside the composite drum device J to a certain extent after the subsequent composite process.
And a polymer recovery device G is further arranged at the feeding position of the polymer material F03, wherein the polymer recovery device G is connected with an air suction device and is used for adsorbing and recovering the excessive scattered polymer material F03.

The too large or too small included angle a can influence the feeding effect of the polymer material F03, namely, the optimal blanking position of the polymer feeding device F on the composite drum device J can be found in the angle range.
In order to ensure that the polymer material F03 enters, the arrangement position of the polymer blanking pipe F1 is matched with the arrangement position of a guide device H described below, so that the polymer material F03 is scattered in the angle range set by the guide device H along with gravity, and most of the polymer material F03 can enter the fluffy non-woven fabric F02, and a small amount of polymer material F03 can fall outside; that is, the angle between the tangent line of the receiving position of the composite drum device J and the line of the tangent point on the circular arc from the receiving position to the mounting end of the air supplementing plate H2 is c, where c=2a. The central angle d corresponding to the arc length of the air compensating plate H2 in the guide device H is related to the gram weight of the polymer material F03 set in the composite core F00, and generally, the larger the gram weight is, the larger the angle d is set (the longer the time of the surface of the composite drum device J, the larger the amount of the polymer material F03 entering is, and conversely, the smaller the gram weight is, the smaller the angle d is set), so the central angle d corresponding to the arc length of the air compensating plate H2 in the guide device H is set to be 60 ° -120 °. And the height e of the polymer blanking pipe F1 and the surface of the composite drum device J should be within a certain range, and the height e is more than 20mm and less than 100mm.
In order to make the amount of the polymer material F03 applied to the bulky non-woven fabric F02 be larger, the outer diameter of the composite drum device J is set to be larger, and because the larger the outer diameter of the composite drum device J is under the same linear velocity, the larger the angle d of the air compensating plate H2 in the guiding device H can be ensured, so that the sufficient bonding time between the polymer material F03 and the bulky non-woven fabric F02 is ensured, and the amount of the polymer material F03 absorbed into the bulky non-woven fabric F02 is also larger, in this embodiment, the outer diameter of the composite drum device J is in the range of 200mm-600mm.

Then, the third semi-finished product F 'is gradually conveyed to a clamping device K of a downstream station, and the third semi-finished product F' is clamped by the clamping device K, so that the core body is more compact, and the fluffy non-woven fabric F02 and the high polymer material F03 can be better fused; and the second fixing adhesive G02 is subjected to hot melting again, so that the bonding strength of the high polymer material F03 is enhanced;
the third semifinished product F' "is then conveyed to the coating device L after the drive nip of the third nip-drive roller C03 and a third fixing glue G03 is applied before the coating device L. The third semi-finished product F 'is coated by a coating plate while the third semi-finished product F' is adsorbed by a vacuum box on the coating device L, and finally a composite core F00 is formed; the edges of the two sides of the composite core F00 after being coated by the coating device L are completely coated and fixed by the third fixing glue G03, so that the leakage of the high polymer material is effectively reduced.
